A letter to the editor is presented in response to an article on retinitis pigmentosa associated with blepharophimosis, blue dot cataract and primary inferior oblique overaction that was published in one of the previous issues.

Examines the benefits of understanding the inferior oblique muscle action on surgical procedure. Occurrence of inferior oblique muscle overaction in patients with congenital esotropia; Consideration of the overaction of the muscles in correcting the horizontal and vertical deviation;...

Purpose: To study the relationship between inferior oblique muscle overaction and astigmatism, and to explore any change in astigmatism after surgery. Methods: This was a retrospective chart review of patients undergoing strabismus surgery. Demographic data collected included age, diagnosis,...

The article discusses a research study on the role of the location of the equator and newly attached inferior oblique (IO) muscle orientation in contralateral inferior oblique overaction (IOOA) development. Study subjects include 14 patients with 5-12 prism diopters (PD) with hyperdeviation in...

A young girl had cyclic esotropia with cyclic inferior oblique overaction and "V" pattern. A recession--resection surgery of the horizontal rectus muscles and recession of the inferior oblique muscles cured the cyclic esotropia as well as the inferior oblique overaction and V pattern.
